Campbell, who worked at NJ Transit for seven years and earned $54,330 annually, resold the tickets between January 2007 and September 2009, prosecutors said.

"When a public employee commits a crime related to his job, he creates two victims — his employer and society," said Assistant Prosecutor Brandon Minde, who handled the case. "With today’s admission of guilt, forfeiture of employment and pending state prison sentence, Mr. Campbell will now be held accountable to both."

Campbell is scheduled to be sentenced on Sept. 17. In addition to an 18-month sentence with a yearlong period of parole ineligibility, the plea agreement permanently bars Campbell from holding a public job and requires him to pay back the $3,500 to NJ Transit, prosecutors said.
